The table shows the difference between vector and scalar quantities. Quantity Description Examples has magnitude only has magnitude and direction Copy the table and complete the first column with the word vector and scalar in the correct rows.

A scalar quantity is defined as the physical quantity that has only magnitude, for example, mass and electric charge. On the other hand, a vector quantity is defined as the physical quantity that has both magnitude as well as direction like force and weight. Quantity Description Examples Scalar Has magnitude only Mass, Electric charge Vector Has magnitude and direction Force, Weight For example, distance is a scalar quantity and displacement is a vector quantity.

A runner travels 400 m in 50 s . What is her average speed?

Distance travelled, s = 400 m Time, t = 50 s Average speed can be calculated by dividing the total distance travelled by the total time. Average speed = Total distance Total time is the required formula. So, average speed, V a v = 400 50 = 8 m / s
